我们考虑麦克斯韦-弗拉索夫理论的轴子扩展的一种宇宙学应用，该理论描述了各向异性膨胀（早期）宇宙中演化的全球磁场状态下的轴子诱导振荡状态。我们证明，相对论等离子体中的协同电场与赝标量（轴子）和全局磁场耦合，在这个三能级系统中发挥着调节器的作用；特别是，协同（弗拉索夫）电场将宇宙膨胀膨胀时期轴子-光子耦合引起的赝标量场的异常增长状态转换为具有有限残余轴子密度的振荡状态。我们分析了相对论等离子体中轴向诱导电场协同振荡的色散方程的解。
We consider one cosmological application of an axionic extension of the Maxwell-Vlasov theory, which describes axionically induced oscillatory regime in the state of global magnetic field evolving in the anisotropic expanding (early) universe. We show that the cooperative electric field in the relativistic plasma, being coupled to the pseudoscalar (axion) and global magnetic fields, plays the role of a regulator in this three-level system; in particular, the cooperative (Vlasov) electric field converts the regime of anomalous growth of the pseudoscalar field, caused by the axion-photon coupling at the inflationary epoch of the universe expansion, into an oscillatory regime with finite density of relic axions. We analyze solutions to the dispersion equations for the axionically induced cooperative oscillations of the electric field in the relativistic plasma.
